flutter应用在三星手机上运行时，屏幕左下角有游戏工具的浮动图标。flutter应用在三星android手机上被识别为游戏？
今日，我用flutter编写一个ios/android应用，并在三星note8上运行时，突然发现应用启动后，屏幕上显示的不是
Flutter Demo Home Page
而是
Welcome to Game Tools
| 我点击屏幕右下角的 < 后，屏幕倒是切换到flutter应用了，然而，屏幕左下角还是比其他应用多了一个图标。即 | 的左侧图标，在其他应用中不会出现，而且，点击该图标后，手机就会启动游戏工具(Game Tools) |
我搜索Stackoverflow后，发现，React Native的应用也有类似情况
React Native app is recognized as a game on Samsung Note8
I think there are few possibilities.
you (or one of your dependencies) have included the google play service API which inside of play service API has a module named games that samsung will automatically treat it as game.
You could find which of your dependency is loading google play service API and create a exclude like:
compile (project ('your.dependency')){ exclude group: 'com.google.android.gms', module:'play-services-game' }
Your application id (can see on build.gradle) is registered on samsung game database. You could check by going into playstore and search for your application id
不过，我检查了flutter的依赖(dependencies)，并没有发现play-services-game。难道，真的是application id被三星识别为游戏的id了吗。
我检查了flutter默认的app id，该id为com.example.app，我将该值改为com.example.app，并重新编译运行应用。结果，我发现，当app id为com.example.app时，三星的游戏工具就会出现，而app id为com.example.app111时，三星的游戏工具就不会出现。
看来，com.example.app的确已经注册到三星的游戏数据库中( is registered on samsung game database. )了。还好，我们正常发布的应用不会使用com.example.app，所以，我们无需担心flutter编写的应用会触发三星的游戏工具(Game Tool)。
